Benefits of technology

The patent text describes new methods and tools for improving image coding and filtering efficiency. This can lead to improved image quality and faster processing times.

Problems solved by technology

As image / video data has high resolution and high quality, the amount of information or bits to be transmitted increases relative to the existing image / video data, and thus, transmitting image data using a medium such as an existing wired / wireless broadband line or an existing storage medium or storing image / video data using existing storage medium increase transmission cost and storage cost.

Abstract

According to embodiments of the present document, information for carrying out in-loop filtering across virtual boundaries can be efficiently signaled. For example, in-loop filtering can be carried out on the basis of signaling of information which is related to whether in-loop filtering across virtual boundaries is enabled or not.

Description

BACKGROUND OF THE DISCLOSUREField of the disclosure[0001]The present document relates to a filtering-based image coding apparatus and method.Related Art[0002]Recently, demand for high-resolution, high-quality image / video such as 4K or 8K or higher ultra high definition (UHD) image / video has increased in various fields. As image / video data has high resolution and high quality, the amount of information or bits to be transmitted increases relative to the existing image / video data, and thus, transmitting image data using a medium such as an existing wired / wireless broadband line or an existing storage medium or storing image / video data using existing storage medium increase transmission cost and storage cost.[0003]In addition, interest and demand for immersive media such as virtual reality (VR) and artificial reality (AR) content or holograms has recently increased and broadcasting for image / video is having characteristics different from reality images such as game images has increased...
